How do I set the selenium webdriver get timeout?

When I am using a proxy in webdriver like FirefoxDriver, if the proxy is bad then the get method will block forever. I set some timeout parameters, but this did not work out.

This is my code:

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("general.useragent.override", ua);    
Proxy p = new Proxy();
p.setHttpProxy(proxy);
profile.setProxyPreferences(p);
profile.setEnableNativeEvents(true);

// create a driver
WebDriver driver = new FirefoxDriver(profile);
driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);
driver.manage().timeouts().setScriptTimeout(30, TimeUnit.SECONDS);
driver.get("www.sina.com.cn")

The call to driver.get will block for ever, but I want it to wait for 30 seconds and if the page is not loaded then throw an exception.

The timeouts() methods are not implemented in some drivers and are very unreliable in general.
I use a separate thread for the timeouts (passing the url to access as the thread name):

Thread t = new Thread(new Runnable() {
    public void run() {
        driver.get(Thread.currentThread().getName());
    }
}, url);
t.start();
try {
    t.join(YOUR_TIMEOUT_HERE_IN_MS);
} catch (InterruptedException e) { // ignore
}
if (t.isAlive()) { // Thread still alive, we need to abort
    logger.warning("Timeout on loading page " + url);
    t.interrupt();
}

This seems to work most of the time, however it might happen that the driver is really stuck and any subsequent call to driver will be blocked (I experience that with Chrome driver on Windows). Even something as innocuous as a driver.findElements() call could end up being blocked. Unfortunately I have no solutions for blocked drivers.
